The target now is to make this light awesome , and correct all the possible flaws it has , as a test unit . So Narsil , even though is awesome it can’t be implemented .
Light has 21 “ultra-low / low” brightness levels to choose from :
From off , click 4 times to get in programming mode . Now , depending in which level you are , a single click gets you to the next brightness level (it’s in cycle , so once you reach the highest , you’re back in the lowest). Longer click saves the level you’re in .
It has some cool sub lumen modes , that even xhp70s can’t light properly all the dies …
I’m trying to guess why the dies do not light up the same…
Small deviations from the specs out of production that make a big difference at very low voltage?
They are all in parallel and they are probably getting a few mA each . Then i think every xhp70 in 12V configuration has 4 dies connected in series (i think). Only if all the 12 dies had same Vf would light equally , theoretically
